The separator separates the low-resolution image generated by the generator into a texture component image and a frame component image. The texture generator generates texture component from the texture component image and the frame component image separated by the separator. The combiner combines the texture component generated by the texture generator with the high-resolution image generated by the high-resolution image generator to generate an output image.Type: GrantFiled: June 27, 2011Date of Patent: July 23, 2013Assignee: Kabushiki Kaisha ToshibaInventor: Yukie Takahashi

Patent number: 8471961Abstract: A video processing apparatus prevents image quality degradation, while reducing motion by combining high-frequency and low-frequency image data at the immediately preceding sub-frame at a first composite ratio ?, generating first-sub-frame image data. By combining low-frequency image data and high-frequency image data at a second composite ratio 1-?, image data is generated as second-sub-frame image data. Then, the second-sub-frame image data is output with their polarity inverted with respect to the first-sub-frame image data. The ratio ? is gradually decreased frame by frame at a first frame group, and the ratio ? is gradually increased frame by frame at a second frame group subsequent to the first frame group.Type: GrantFiled: December 16, 2010Date of Patent: June 25, 2013Assignee: Canon Kabushiki KaishaInventors: Shinichi Uemura, Yukihiko Sakashita

Patent number: 8462268Abstract: Embodiments of the present invention may provide a clock and timing generation scheme for a video signal processor (e.g., a scaler), which enables fast switching between different input video standards without disturbing the output clock or timing. The scheme also may minimize the number of video frames that are dropped or repeated at the output. This may be achieved by locking the video's output timing to the input timing and also by utilizing a frame buffer to remove instantaneous discontinuities caused when an input is changed.Type: GrantFiled: December 10, 2010Date of Patent: June 11, 2013Assignee: Analog Devices, Inc.Inventors: Seamus Ryan, Weijun Xu, Tianjiang Li, Wei Che, Niall O'Connell

Patent number: 8462273Abstract: The image display device and the like may generate an OSD image with the contents at the time of temporary non-display instruction when there is a redisplay instruction after temporary non-display instruction of a normal OSD image. As a result, the user can perform adjustment and the like of an image using an OSD image more efficiently. Since the image display device and the like generate a second OSD image showing temporary non-display at the time of temporary non-display of a normal OSD image, the user can see that the normal OSD image is in a temporary non-display state. In addition, since the size of the second OSD image is small, almost the entire original image can be checked.Type: GrantFiled: August 13, 2009Date of Patent: June 11, 2013Assignee: Seiko Epson CorporationInventor: Osamu Kumamoto
